|Jul-20-10|| ||Patriot: <<randomsac>: Ah opening traps. This puzzle is a reminder for me not to blaze through an opening otherwise bad stuff happens.>|
Basically I think it is ok to blaze through the opening as long as familiar moves are being played or everything is "in book". But when your opponent plays something different then it's time to SLOW DOWN and see if their move is safe or how you might refute it. See how the move changes the position from the tabiya and it could be their move was a mistake.
Essentially, the first move that is "out of book" becomes the first critical move of the game.
|Jul-20-10|| ||Once: <Patriot> Wise words, my friend. |
I like to think that there are two opening phases in a chess game.
The first opening is when I am operating purely on memory. Then I know I am safe. I can bang the moves out with confidence as if I were Kasparov or Casablanca reborn. My 1. e4 is the stuff of legend. As Irving Chernev said in Logical Chess, you can play this move with certainty that no grandmaster alive or dead could play a better move.
The second opening starts when my opponent plays something that I do not know. Then I have to think for myself. Now comes the time for thinking and watching out for traps. If my opponent has played something out of book, then maybe he has made a mistake that could be exploited? Or maybe he knows the opening better than I do?
But other than that, this second opening is a time to develop pieces, don't go grabbing pawns, castle, and decide where the rooks are going to go.
This phase ends when the opening becomes a middlegame, ie when the pawn structure is more or less established and the rooks have something to do.
GMs have long long first openings, sometimes all the way into a middlegame or even an endgame. Us patzers quickly find ourselves in phase 2.
That's why I like opening books with lots of text to explain the middlegame plans. Okay, I've run out of memorised moves. Now what do I do?
In today's game, it seems that white made the mistake of thinking he was in the first opening, when in fact he was in the second.
|Jul-20-10|| ||Once: <scormus>
The scene: a wood somewhere in Germania. The Roman army are arranged for war - catapults to the rear, then archers, then the foot soldiers. Nearby, the cavalry are hidden by thicket of trees. Maximus picks up a handful of earth and rubs it between his fingers to remind himself of his farm in Spain where his wife and son wait for him.
Suddenly, a horse gallops from the far side of the wood, its headless rider tied to the saddle.
"They say no," says Maximus, with a hint of sadness in his voice. He has seen too many battles to be either afraid or to relish another.
"Some people don't know when they're beaten," says his lieutenant.
"Would you?" asks Maximus. "Would I?"
|Jul-20-10|| ||chrisowen: Having row of fourth pieces with un-castled king spells danger. Try angle e7e5 Bxe5 with cat and mouse playing Qa5+. Pool the trap usually manky Bg5, and the pacemakers it's gonna be alright? Here black picks the cherry tree dead invicta Z Djordjevic vs M Kovacevic, 1984 or gnothi seauton fuss knight in R F Combe vs W Hasenfuss, 1933. Bf4 Nxd4 miles from the truth it abases general principles on good grounds. 19..f5 cross off score e5 the grand instigator crock him.|
|Jul-20-10|| ||kevin86: An easy one;black takes advantage of the exposed pieces by fork and fork!|
The pawn at e5 is immune owing to 5...♕a5+ picking off the bishop.
The play is hopeless after move five!
|Jul-20-10|| ||Marmot PFL: Clever trap, that I hadn't seen before.|
|Jul-20-10|| ||beenthere240: From the 5th move on,it's apparent that having an extra piece is a major plus for black.|
|Jul-20-10|| ||Jack Kerouac: Roberto needed Rosary at the Rosario.|
|Jul-20-10|| ||YouRang: Move #4, eh? I wonder if that's a record for earliest puzzle.|
I figured that ...Qa5+ was probably part of the solution, although playing the immediate 4...Qa5+ doesn't work so well, since 5.Bd2 or 5.Qd2 or 5.Nc3 or 5.c3 all get white out of trouble (note that 5...e5 can be answered with 6.N4b3 attacking the queen.)
However, the queen check would have teeth if it could attack another piece. As soon as that idea came to mind, I spotted the pawn fork <4...e5> as a decoy that sets up the queen fork: 5.Bxe5 and *now* Qa5+ scoops up the bishop for a pawn.
Nothing worse than getting zonked right in the opening.
|Jul-20-10|| ||scormus: <Would you? Would I?> The fundamental question in all cases of conflict.|
e.g. after 4 ... e5, the conversation might have gone ....
Oscar: Oh dear, I've wasted a piece. Indeed, my situation is serious, but it's not hopeless. I'll play on.
Roberto: That's where you're wrong my friend. Your situation is hopeless, but it's not serious. So play on.
|Jul-20-10|| ||zooter: 4...e5 forking knight and bishop and if 5.Bxe5 Qa5+ picks up the bishop|
Time to check
|Jul-20-10|| ||MaczynskiPratten: My first thought was that White was rather rude not to resign immediately at move 4 or 5, as in the neat examples quoted by <chrisowen> (thanks Chris, I was trying to remember the 3 mover, you saved me the search). But then some kibitzing led me to Shumov vs Jaenisch, 1851, where a strong Black player wins a piece in a virtually identical trap, but loses the game!|
|Jul-20-10|| ||MaczynskiPratten: Or, from a different perspective, Grau exploits his extra piece very neatly and effectively here, to avoid any swindles.|
|Jul-20-10|| ||JG27Pyth: I should have solved this in a mirror -- I used a homegrown sort of retrograde analysis for this one... pretty much did the whole thing backwards:|
So I look at the position briefly and try to solve White to win, fail, but I'm called away from my desk and as I leave i think... could be black to play, check that... and I think, but if it's black to play it just has to be a Qa5 check-fork puzzle... I return to my desk see that it's black to play, ahah.... then I see that Qa5+ doesn't win a piece.... hmm... finally I notice the pawn forkability of the two minors which decoys the bishop to the 5th rank, there we go. So it is a Qa5+ fork ...
|Jul-20-10|| ||cjgone: I luckily did a puzzle about pinning two pieces with a pawn earlier in the week making this one come out very quickly. And even if the pawn is taken, the check by the queen comes sweeping in.|
Thank god for Tuesdays. :d
|Jul-20-10|| ||WhiteRook48: 4...e5 puzzles are easy to solve if you've seen the solution before|
|Jul-20-10|| ||TheBish: O Garcia Vera vs R Grau, 1929|
Black to play (4...?) "Easy"
Black wins a piece with 4...e5! 5. Bxe5 Qa5+ and 6...Qxe5.
|Jul-20-10|| ||chrisowen: <MaczynskiPratten> Dare devils lead the way. A small amount of ferreting for pad and pen work 20 min. Reversing the trend my idea take a pole catalog few genre droppings counting in pointing out the traps. It is beverly hill cop kinda role. As Black footed his snout in front, White put up no skirmish.|
|Jul-20-10|| ||wals: Thank heavens saw this sitter but not to the end.
4.Nxd4 -1.90 was the first of White's blunders (Qxd4 or Bxb8 better) culminating with 19.Qf1 -13.10.
Qc1, -3.65, would have been the best
futile survival effort.
Rybka 3 1-cpu:
|Jul-20-10|| ||ZUGZWANG67: Of course 4...e5, when after 5.Bxe5 follows 5...Qa5+ and 6...Qxe5.|
|Jul-20-10|| ||turbo231: got it but it took too long so i didn't really get it|
|Jul-20-10|| ||rapidcitychess: 4...e5 5.Bxe5 Qa5+
Ok,come on let's be real, that was too easy.
|Jul-20-10|| ||Brandon plays: lol, I think I would've missed this in a blitz game most likely. I was thinking it had to be something to do with Qa5+ and then e5 popped into my mind. Game!|
|Dec-16-14|| ||FSR: I love this trap. I've pulled it off at least thrice in blitz games - including one a moment ago.|
|Dec-26-14|| ||FSR: An online blitz opponent just fell into a weird version of this trap against me on instantchess.com: 1.d4 c5 2.Bf4? cxd4 3.Be5?? Qa5+. The game continued 4.Nbd2 Qxe5. Now my opponent requested that his last move be canceled. Bemused, I agreed - he's still down a piece after all. He then requested that we return to the position after 1.d4. I declined. He then invoked his right to cancel the game entirely! Great rule you've got there, instantchess.com!|
